- water shortage during pregnancy - to which it can lead?
- amniotic fluid, its composition and functions
During pregnancy, the baby is in a liquid-filled cavity, called the amniotic sac.The walls of the amniotic sac consisting of two membranes - chorion and amnion.Before birth, they are broken and the amniotic fluid flows out - this is called a withdrawal of amniotic fluid.
amniotic fluid serves several important functions:
- protect the child from various damages, for example, in cases where a pregnant woman gets a punch in the stomach, or other injuries.
- helps to develop the baby's lungs and digestive system.
- protects the baby from infection.
child regularly ingests a certain amount of amniotic fluid, and it is derived from the mother's body in the form of urine.Thus, the level of the amniotic fluid varies daily.
volume of amniotic fluid increases with pregnancy.Of only a few milliliters in early pregnancy, it increases to 800-1000 ml of the thirty sixth week
How is oligohydramnios?
doctor may suspect oligoamnios if, according to the ultrasound, body length and weight of the child is too small in comparison with the average for a given gestational age.
increased likelihood of water scarcity in women who have faced such violations during a previous pregnancy and / or who have had babies whose weight was below normal.Such women and expectant mothers, who have disorders of blood pressure, lupus and other diseases, further examined to identify water scarcity.
During ultrasound measure the depth of the four pockets of amniotic cavity and folded the values obtained, calculate the amniotic fluid index (AFI).Each week of pregnancy corresponds to a certain index AFI.Small deviations are permitted, however, a big difference from the norm indicates the presence of a problem.
reasons for water scarcity
addition withdrawal of amniotic fluid, can cause oligohydramnios:
- Problems with the placenta
- Medicines that takes expectant mother
- health problems in a child
The withdrawal of amniotic fluid
Water may depart promptly, immediately and in large volumes, and can be - very slowly, gradually.Sometimes they can be mistaken for an episode of urinary incontinence which is often observed in the later stages of pregnancy.
If you suspect that your water breaks, but are not sure, contact a doctor in.If this happens too early, you will probably be discharged medication to prevent infection.Depending on the duration of pregnancy after the withdrawal of amniotic fluid doctor may suggest that you call the delivery with the help of drugs, or to wait a bit.In the latter case, the child should be checked regularly prior to delivery will begin in a natural way.
Problems with the placenta
water shortage can be caused by a condition in which the placenta can not provide the child with enough blood and nutrients.This happens, for example, lupus, high blood pressure, pre-eclampsia and diabetes.The poor functioning of the placenta will inevitably affect the development of the child.If such violations doctors constantly monitor the health of mother and child and sometimes prescribed special treatment.
Some drugs may cause oligohydramnios.They include angiotensin-converting enzyme (ACE) inhibitors - drugs used to treat high blood pressure Blood pressure - dangerous if his swing? , and non-steroidal anti-inflammatory drugs such as ibuprofen Ibuprofen: anti-inflammatory drug .Typically, these drugs are not appointed during pregnancy.
health problems in a child
Low levels of amniotic fluid can be related to the fact that the child's body does not produce and does not take sufficient urine.This may be a sign of its existing disorders of the kidneys, heart, or chromosomal abnormalities.
